Ankara vowed to reveal all the details of its own inquiry as US President Donald Trump said he was unsatisfied with Saudi Arabia's response to the columnist's death while the EU, Germany, France, Britain, Australia, Canada and the United Nations also demanded greater clarity.
The senator added the United States should discontinue its arms sales to Saudi Arabia and have a serious discussion with Riyadh about "whether or not they want to be an ally or they want to be an enemy". Saudi Arabia said 18 Saudis were arrested and several top intelligence officials were fired.
Campaigning for her party in a regional election, Merkel repeated to a news conference her earlier condemnation of Khashoggi's killing, which Saudi Arabia admitted had taken place inside its consulate in Istanbul. He also said Prince Mohammed was not responsible.
Sawyers said the fate of Khashoggi - whom Turkish authorities say was killed inside Saudi Arabia's consulate in Istanbul - was a wake-up call to the Trump administration about "just how unsafe it is to have people acting with a sense that they have impunity in their relationship with United States".
Khashoggi, a resident of Virginia, vanished on the afternoon of October 2 after entering the Saudi Consulate to obtain documents that he needed to remarry. President Trump appeared to initially accept the Saudi explanation, but US lawmakers, intelligence officials and foreign policy experts quickly accused the government in Riyadh of a coverup.
Kushner was heavily involved in making Saudi Arabia Trump's first stop on his maiden global trip as president a year ago.
A Saudi official told Reuters separately: "A group of Saudis had a physical altercation and Jamal died as a result of the chokehold".
Guterres "stresses the need for a prompt, thorough and transparent investigation into the circumstances of Mr Khashoggi's death and full accountability for those responsible", spokesman Stephane Dujarric said in a statement. Saudi Arabia's preliminary investigation "demonstrates the Kingdom's keenness and commitment to finding the truth of this incident and taking the required legal action against those involved", Egypt's Foreign Ministry said in a statement.
In a recent off-the-record interview published posthumously by USA magazine Newsweek, Khashoggi described the 33-year-old heir apparent as "an old-fashioned tribal leader", but said he would have accepted an offer to work as his adviser.
The king also ordered the formation of a ministerial committee headed by Prince Mohammed to restructure the general intelligence agency, state media said, suggesting the prince still retained wide-ranging authority.
"Do I think he did it?"
Saudi officials have roundly denied that the crown prince had any involvement in the affair. In the past, military exports by Berlin to Saudi have mostly consisted of patrol boats. There was a standing order to bring critics of the kingdom back to the country, he added.
"The crown prince was not aware of this [operation]". A member of the team then dressed in Khashoggi's clothes to make it appear as if he had left the consulate. "We're going to find out who knows what, where and we'll figure it out", he said, indicating that things might be clearer by Monday.
The public prosecutor's statement did not specify where the operatives had put Khashoggi's body or if they plan to inform the Turks.
Democrats have repeatedly lashed out at Trump's response as weak and indecisive, and they said his latest reaction fell short as well.
